Solar panel cleaning in Knoxville

Overview

What the job actually involves

Pollen, dust and bird mess shade the cells on a solar array, and shading one cell drags down the string it belongs to. Cleaning an array is a light-touch job: deionised water, a soft brush on a pole, no detergent and nothing abrasive anywhere near the coating.

We clean from the ground or the roof edge with poles wherever we can, because walking on panels is the fastest way to create micro-cracks that never show up until an inverter starts reporting faults.

Step by step

How we run a visit

Four or five steps, the same every time, so you always know what happens next.

  1. 1

    Survey and photograph

    We record array condition and note any cracked cells or loose clamps before touching anything.

  2. 2

    Rinse

    A deionised water rinse loosens pollen and dust so the brush has less to do.

  3. 3

    Soft brush

    A soft pole brush works row by row, with no pressure on the glass and nobody standing on panels.

  4. 4

    Final rinse and report

    Pure water rinse dries spot-free, and you get before and after photos with any issues flagged.

Why bother

What you actually get

  • Cells stop being shaded

    Soiling losses in our region typically run in the single digits, and cleaning recovers most of that (sample figure, your array will vary).

  • Warranty-safe method

    No detergents, no abrasives, no pressure washing, which is what most panel warranties require.

  • A second set of eyes

    Photos of loose clamps, lifted flashing or damaged cells give you time to call your installer.

Questions

About this service

All questions

Once a year suits most Knoxville homes, twice if your array sits under trees or near a gravel road.

No. We use pure water and soft brushes only, which is the method most manufacturers specify. We never pressure wash panels or walk on them.

That depends entirely on how dirty the array was. Published industry figures for our climate sit in the single digits and we do not promise a number.
